This article is meant for users of CodeTwo Email Signatures for Email Clients. This software has been discontinued. If your organization uses Microsoft 365 (Office 365), check out CodeTwo Email Signatures 365.


Despite setting an appropriate option in the CodeTwo Email Signatures for Email Clients application, the signature is not set as a default one in Outlook. This happens in a case when the Outlook profile has been created by a third-party software, such a G Suite Sync for Microsoft Outlook (GSSMO) (formerly Google Apps for Microsoft Outlook a.k.a. GASMO) which did not properly modify Windows Registry. As a result, you need to manually include the signature while composing a message.

  6. Create a new expandable string value entry (REG_EXPAND_SZwith name ReplySignature. As a value set the name you have noted in step 2.
  7. Restart Microsoft Outlook.

From now, your signature should be automatically included while either composing a new message or replying on a existing message.
